Fig. 18, is a view of a die press showing the manner in which the rubber or rubbercontaining parts in the various forms of the severa-l torpedoes forming the subject of my invention may bel extruded through a suitable die and subsequently cut into sections of the desired size, shape and character for cooperative engagement with the shells or casings receiving the detonating material.

In Figs. 1, 2 and 3, of the drawings, I have illustrated a member or carrier for a ody of detonating material, comprising` a cross-strip or band 1 provided at its ends with ears or upstanding projections 2, and beloivthe same, rail-engaging members 3; the latter being preiferably7 corrugated, as indicated at 4, to increase their frictional engagement with a rail-head. The upstanding ears 2 may be recessed as indicated at 5, to receive the ends of a container for a detonating charge; the container, shown in the present instance as tubular, being indicated at 6, and receiving a charge of detonating material, indicated at 7 in the sectional vieiv. The container may be cemented to the web or strip 1 and to the sockets or recesses 5 Which receive its ends by any suitable cementing material available for the purpose, and when suoli cement is dry, the torpedo is ready for use.

e containers 6 may be made of any suitable material, although they are preferably made of a rubber or ubber-eontaining body Which may be extruded from a die press While the material is in a plastic state, or they may be specially formed by other or rubbercontaining material, such for instance as pasteboard, paper, fabric or like. In the latter instances the material employed is of a Waterproofv nature or is Waterproofed beg ears or shoulders, may be arranged as shown at 2a in Figs. t, 5 and (i, and provided with in-l wardly projecting lugs 10 for engagement with recesses 11 provided in the ends of the shells or casings 6a, adapted to receive charges of detonating material.

Another arrangement or modification, shown in longitudinal section, Fig. 7, and in cross section, Fig. 9, consists in providino' a continuous strip 12 connecting the tops of' the upstanding ears or projections 2", which strip is designed to overlie the container 6b for the detonating material; the ends of the latter engaging lugs 10a on the inner faces of the earsV o assist in retaining the detonating charge containers in place, the ears 2C of the structure shown in longitudinal section, Fig. S, and in cross section, Fig. 10, may have its cooperating lugs 10b dovetail in shape, so as to wedge in the end of the detonating charge container G. y

A further modification of my invention in Figs. 11, 12 and have shown a strap 1a carrying rail-engaging' lugs 3a, Which strap is adapted for insertion in the container 6d, asclearly shown in the sectional views, Figs. 12 and 13; Y such arra gement bringing` the lugs 3a in proper position for engagement with the head of a rail, in the manner illustrated With respect to the other forms of torpedoes shown. The container Gd for the detonating charge is shown in Fig. 11 as of cylindrical form, but it will be understood that containers havin a diiferent cross section may be employed, and in 4i0'. 1%, I have shown a container (-3e adapted to receive the lug-carrying strap band having a in the form of a In finishing a ends of the container and sealed to the strap 1EL 3a, as illustrated in Fig. 12.

In Fig. 15, I have shown a structure comprising a rail-engaging lug 3b formed continuous with an upstanding ear or member d having an inwardly projecting lug Y which, When employed in pairs in connection with a detonating charge container, such for instance as indicated at Gf in Fig. 17,

the latter tion, any integral connection between the respective rail-engaging lugs is omitted, and the detonating charge container is depended upon to aiford the desired connection and impart to the torpedo that degree of rigid- In Fig 16, I have shown another member capable of use in the manner illustrated withA reference to the structure shown in Fig. 15@` n this structure, which may be made of made vot a plastic body such as rubber or y rubber or rubber-containing material, or any other suitable material and comprises an ear 2e with ain inivardly projecting lug 10d, a metallic piece l5 is combined, preferably ot lead, which may i'orm a rail-'engaging member designed to hold the finished structure to the head oi' a rail.

The rail-engaging-lug-carrying portions of the several forms oi' torpedoes illustrated in VFigs. 4, 5, 7, 8, 11, 12, 15 and 16, when rubber-containing material, may be eX- truded through dies from presses oi usual form well known in the rubber art, in the manner illustrated in llig. i8, which shows the extrusion of a strip from which members such as illustrated in Fig. il, maybe cut; the extruded body or strip being separated into sections of desiredsize by suitably disposed cutting meansai'ranged to operate at regular intervals, thereby providing carrier sections of the desired size and form to be subsequently connected with the containers for the charges of detonating material to form the iinished torpedoes. These sections of rubber or rubber-containing material may be cured in any approved manner, and the rail-head-engaging lugs 3, 3a, 3b, etc., may be shaped by rounding the corners of the same, although this shaping operation is not essential to the construction or proper operation of the torpedo.

ln speaking of the carrier structure or the container for the detonating material as made oit rubber, it will be understood, of course, that what is meant is a rubber-containing material, the portion of rubber in which may be relatively small. The object is to provide a relatively flexible structure suitable for the purpose and one that will be non-iiying and therefore not dangerous under the explosion oli' the detonating charge. The connection between the railengaging lugs and the strip 1, la, &c., to which they are attached may be of a relatively etter grade of material than said strip so as to insure the resiliency required of these lugs and at the same time the desired tension when they are placed in the rail-engaging position.
